          Easiest way to sand ever! This is my first time...
          Easiest way to sand ever! This is my first time doing DIY home improvements and I don’t mean simple tasks. I’m doing the hard stuff. I have a sander but sometimes hand sanding is more practical. This sanding sponge is a dream. I saw it on a YouTube post, thought I’d try it and now I’m hooked. Makes sanding easy and you control just how smooth you want your surface. Highly recommend

          grit comes off sponge after minimal use
          I bought to sand balusters on deck railing. After sanding less than 60 seconds just to see if the grit was too aggressive for the soft pine, I looked at the sponge and noticed a smooth section. I rinsed it to make sure it wasn't full of dust, but no- the grit had come off- completely smooth.

            Great sanding spong for paint prep
            [This review was collected as part of a promotion.] I really like these 120 grit sanding sponges for prep work on wood trim and door jams before painting. The dust channels help keep the grit surface clean and helps with the longevity of the grit. This is one of the best products to use when you need to sand by hand.

              Great Sand
              [This review was collected as part of a promotion.] Great Sanding Sponge, I hace a full Stainless Steel grill thad I like to keep shiny and this sponge make the job a lot easier. Interested of using sand paper, this Sand Sponge works perfect to dand all the surfaces and keep everything smooth and the easy to just wash it on the sink. We love it, they last forever.

                Durable sanding sponge
                [This review was collected as part of a promotion.] I got this sanding sponge a few weeks back to help with all of the drywall work I've been doing as part of a bathroom renovation in my house. I've used a ton of different sponges in the past for other projects around the house, and none of them have lasted as long as this one did. In my (admittedly small) bathroom, I used this one sponge to sand down newly-mudded areas on three walls and the ceiling. After a couple hours of scrubbing and sanding, the sponge was still abrasive and getting the job done. It's amazing what a difference a well-made product can do to make your life easier!

                  3M is the best! Great sanding blocks.
                  [This review was collected as part of a promotion.] I've been using sanding block for decades and 3M always has the best and longest-lasting ones. What makes this one unique is the genius new design that incorporates channels on the back side to allow sawdust and drywall dust to be channeled away instead of creating a big dust cloud. Such a small innovation and change in design makes a huge difference when you use this sanding block.
                    Sturdy and strong
                    [This review was collected as part of a promotion.] I do a lot of DIY projects and sanding sponge is a must especially when I paint my house. I used this 3M pro grade precision dust channeling sponge when I was painting my living room. It worked great. I had to smoothen the wall a lot since it had a lot of nail holes which I had to patch up. It’s a very sturdy sponge and also the dust is not much at all. I like the concept of dust channels as it routes the dust away. 120 grit is perfect for my use and the grip is great. I am very happy that this prepares my wall for painting.

                      Great sanding block
                      [This review was collected as part of a promotion.] This 3m sanding block is great. It is super light weight and portable for quick projects around the house. The block has grit on all 4 sides, so you can really get good use on all sides. The front has the grooves to collect dust but the back is standard(flat) which is just another option. The block is a bit spongey which allows you to bend it into cracks and crevices for sanding. Overall it is a quite versatile and durable tool to add to the arsenal for quick home projects.

                        Channeling dust in all the right places
                        [This review was collected as part of a promotion.] I use 3M products all the time and these sanding blocks are great. They can be used for finishing touches on wooden furniture or using them on drywall for sanding and doing a small repair. One side has a dust channeling feature and the other side has a flat surface so its very versatile depending on the project you are using it for.

                          Unique product that works extremely well!
                          [This review was collected as part of a promotion.] I recently painted my room and the Dust Channeling Sanding Sponge by 3M was just the product I needed to complete the job perfectly. After using spackle to repair holes in the wall, the Sanding Sponge helped me create a smooth surface and the unique dust channeling grooves helped dissipate the dust away from the wall, which is unlike any other sanding product I have ever used. The sponge is also flexible enough to make it perfect for sanding those hard to reach suraces. Unlike sanding paper, this product fits securely and comfortably in you hand allowing for easier sanding and covers a larger surface area getting the job done quickly. I would definitely recommend this product!
